'An Invisible Sign'

Pretty much "Freedom Writers" crossed with "A Beautiful Mind," this drama provides Jessica Alba an atypical role as a woman obsessed with math and numbers.

She gets an opportunity to use that knowledge as a teacher, but she has fear of entering a world where she'll be forced to be social - with a fellow educator (Chris Messina, "Julie & Julia") being one of those who could bring her out of her shell. J.K. Simmons ("Juno") and Sonia Braga also star. *** (PG-13: AS, P) (Also on Blu-ray)
